All hadith

'Irbad bin Sariyah (May Allah be pleased with him) reported: One day, Messenger of Allah (ﷺ) delivered a very effective speech, as a result, eyes shed tears and hearts became softened. A man said: "O Prophet of Allah! It sounds as if this is a farewell speech, so advise us." He (ﷺ) said, "I admonish you to fear Allah, and to listen and obey even if a black slave has been appointed as your leader. For whoever among you lives after me will see much discord. So hold fast to my Sunnah and the Sunnah of the Rightly-Guided Caliphs who will come after me. Adhere to them and hold fast to them. Beware of Bid'ah (in religion) because every Bid'ah is a misguidance."

'Umar bin Al-Khattab (May Allah be pleased with him) reported: I sought permission of the Prophet (ﷺ) to perform 'Umrah, and he granted me leave and said, "Brother, do not forget us in your supplications." I would not exchange these words of his for the whole world.Another narration is: He (ﷺ) said, "Include us, my brother, in your supplications."

Salim bin 'Abdullah bin 'Umar (May Allah be pleased with them) reported: When a man was to set out on a journey, 'Abdullah bin 'Umar (May Allah be pleased with them) would say to him: "Draw near so that I may bid farewell to you as Messenger of Allah (ﷺ) used to bid farewell to us. (The Messenger of Allah (ﷺ) used to say: "'Astaudi'ullaha dinaka, wa amanataka, wa khawatima 'amalika' (I entrust Allah with your Deen, your trust and your last deeds)."
